Question

A particle is to move in an
xy
plane, clockwise around the origin as seen from the positive side
of the
z
axis. In unit-vector notation, what torque acts on the particle if
the magnitude of its angular momentum about the origin is the
following. (Use the following as necessary: t.)

(a) 8.0 (kg
� m2/s)
? = (N
� m)

(b) 8.0t2 (kg
� m2/s)
? = (N
� m)

(c) 8.0
